两相无刷直流电动机及其系统仿真

A Novel Structure Two-Phase Brushless DC Motor and the System Simulation

两相无刷直流电动机控制简单,成本低,但转矩脉动大,制约了其应用。为此,该文在对其定、转子结构、绕组接线方式、位置传感器放置及工作原理进行分析的基础上,利用Mat- lab建立了电机及其驱动电路系统的仿真模型。分析及仿真结果表明,所研究的两相电机能产生平均转矩运行,有实际应用价值。

A novel structure two-phase brushless DC motor was presented in this paper. Based on the discussion of the stator and rotor structure, armature winding connection, position sensor placement and the operation principle of the motor, the simulation model was established for the motor and drive circuit with Matlab. The simulation results indicate that the proposed motor can produce constant torque and can be used for practical application.
